This is an addon that requires the Embers of Rage DLC, it buffs the Whitehoof racial talents in several ways, here is a list of all the changes made:

Increases the death momentum charges gained by leveling "Whitehooves" from 1 - 5 to 3 - 7
Increases the Strength/Magic gained by leveling "Whitehooves" from 2 - 10 to 3 - 14
Increases the flat damage reduction of "Dead Hide" from 1 - 5 to 3 - 6, in addition to now scaling with Strength for even more damage reduction
Gives "Dead Hide" a passive 20% - 80% pin resistance
Lowers the cooldown of "Lifeless Rush" from 52 - 21 to a flat 25, as well as increase it's duration from 3 - 10 to 5 - 11
Lowers the cooldown of "Essence Drain" from 49 - 33 to 40 - 28

Should work perfectly fine with addons that make Whitehoof playable in the main campaign too.
